NEWSPAPER-STACKING MECHANISM.

Application filed August 28, 1920. Serial No. 406,579.

T all whom it may concern:

Be it known that I, SEVERIN HALvoRsEN,

a citizen of the United States of America,

and resident of the city of Seattle, in the county of King and State of Vashington, have invented certain new and useful Improvements in Newspaper-Stacking Mechanisms, of which the following is a specification. I

My invention relates to mechanisms for delivering and stacking newspapers. It has been designed chiefly for use in connection with a newspaper stufiing machine, but it is evident that it might be employed for other analogous uses. The device is intended to receive a series of papers as they are delivered successively, as from a newspaper stuffing machine, or from any analogous source, and to stack the same in an orderly relation, so that they may be removed in bodies containing a considerable number of papers at the same time. I I

Theobject of my invention is to provide a machine for doing this work which will perform the work in a more perfect manner than the devices previously used for like purpose, and one which is particularly adapted for handling the papers as delivered from a newspaper stufiing machine.

One of the objects of my invention is also to provide a device of this sort which will receive the papers from a carrier or con veyor, one at a time, and which will add these papers as received, to the bottom of a stack of papers, whereby the stack of papers is gradually built up from the bottom and with the papers lying in horizontal planes. Other objects of my invention will be disclosed by an inspection of the drawings and a study of the description thereof contained in this specification.

My invention consists of the parts and combinations of parts which are herein illustrated and described, and which are particularly pointed out in the claims which terminate this specification.

The accompanying drawings show the manner of employing my invention in a 50 structure which is that now preferred by Figure 1 is a top or plan view of the delivering and stacking mechanism.

Figure is an and elevation, or view taken.

inline with the conveyor which delivers the papers to the stacking machine.

Figure 3 is an elevation showing the back side of the device.

-Figure 41- is a sectional elevation taken upon the plane indicated by the line 4 4 of Figure 1.

Figure 5 is a detail view showing a part of the mechanism, the same being taken upon a plane 5-5 of Figure 1.

The particular type of mechanism with which the device, as herein shown, has been designed to operate, is the newspaper stuffing machine of the type of construction shown in my application, Serial No. 290,184, and the improved form thereof shown in another application 406,578, which is filed coincidently herewith. It is, however, usable with other types of apparatus.

In this type of machine, different sections of the paper are combined to form the stuffed paper while being conveyed through an assembling chute or trough in' a horizontal direction. device, as shown in my said application 406,578. which is filed coincidently herewith,

of this assembling chute and of'the papers, as they are being passed thereto, is approximately horizontal. Toobtain certain advantages the general plane of this chute and of the papers has been tilted, so as to make a comparatively small angle with the horizontal, but it approaches the horizontal plane much more nearly than it does a vertical plane. The angle of the bottom surface of this chute is shown by the dotted lines at A in Figure 2, which indicate the bottom plate of this chute.

The means employed in the machine above referred to for conveying the assembled papers lengthwise of the chute, includes an endless belt or chain 1, which passes about wheels 10 at each end of the chute, whereby the same is driven in a steady continuous manner. As a means for engaging the papers to insure that they be carried along and positioned relative to the. other parts in proper position for receiving the various sections, I employ a set of fingers, as 11, which project from the chain and through a slot in the fioor of the chute a sufficient distance to engage the following or rear edge of the papers to insure that theybe c rried. al ngthe general plane In the latest form of this which are beneath the papers.

( s ins rose In employing this form of conveying means there is a tendency for the propelling fingers 11, as they pass about the wheel 10 at the delivery end of the conveyor, to press down upon the papers and thus cause trouble, either by tearing or deforming the papers. One of the objects of my invention is to provide means whereby the papers, as they reach the delivery end of the conveyor and just before being discharged therefrom, are. hen an accelerated feed movement, sufficient to cause them to leave behind the fingers 11, which have heretofore propelled them, and get out of the way of the feed fingers before they start turning about the wheels 10. The manner of securing this result is best shown in Figures 1, t, and 5.

At a level to come below the bottom plates 12 of the assembling trough, are placed feed tapes or belts 21, which are mounted upon wheels or rollers 20 so that they may turn freely. These form supports for the papers during the transfer thereof from the conveyor of the shifting machine to the paper stacking device. Jonrnaled above the assembling chute of the stuffing machine and extending across thesame, are two shafts 21, and 22. The shaft 21. is a fixed shaft which functions mainly as a support for other parts. The shaft 22 rotates and has thereon. pulleys 23, over which pass accelerating belts 24. These belts also pass over rollers 25, which are supported above the belts 21 These pulleys or rollers 25 are journaled upon the outer or swinging end of arms 26, which are pivotallv mounted concentric with the shaft 22.

These levers are, however, not carried upon the shaft 22 but upon flanged bosses 27 carried by the lower end of the arms 27, which arms are secured to and supported from the non-rotative be or shaft 21. The arms 26 are yieldingly forced downward by the ac tion of torsion springs 28, one end of which is secured to the arms 27 and the other to the arms 26. The downward movement of the arms 26 is limited by means of stops carried respectively by the arms 26 and 27. Such stops are more clearly shown in Fig ure 5, consisting of an arm 29 carried by the arm 27 and extending therefrom, and a bolt 29 carried by the arm 26. By this manner of construction the weight of. the arms 26 does not act in any way to produce friction to retard the turning of the shaft 22.

The means by which the shaft 22 is turned and the belts 24: are driven, is so proportioned that the speed of movement of the belt 24, and also of the belt 21, is materially greater than the speed of movement of the conveyor chain 1. The point where the two belts 24 and 21 come close together, being the point where they engage the papers, is located just beyond the end of the conveyor chain 1. It is, however, so placed that these belts will engage the papers so as to accelerate their movement before the paper moving finger 11, carried by the conveyor chain, starts to makethe turn about, the wheel 10. In consequence, the belt will be accelerated and driven ahead of the fingers 11, so that when said fingers start to sweep about the wheel 10, the paper will have been moved out of engagement therewith.

The paper, as discharged from the conveyor chain, is received upon a plate 3. This plate is shown as more nearly ap' proaching a horizontal position than the lower side of the assembling chute. This is a matter which is, however, not strictly essential, although, I prefer to so arrange matters. The plate 3' is supported in such a way as to move freely up and down. The supporting means illustrated consists of a plunger 30, which is mounted to vertically reciprocate within a stop guide, as 31. At one side it is shown as having a pin 32 projecting and engaged by a link 33, whichlink is connected with an arm 3% secured to, or mounted upon, a shaft 35. The manner of operating this herein shown, consists of securing to the arm 34, or to the shaft thereof, a short arm 36, which is connected with a rod, as 37, reciprocated by any suitable mechanism. The manner of reciprocation of the plate consists of a quick uplift, followed almost immediately by a drop to its normal position. The plate 3 will remain long enough in its lowered position, or that shown by full lines in Figure 2, to receive the next paper discharged from the assembling chut The plate 3 is enclosed by guide and retaming fingers or posts, as at, which enclose the papers as they are stacked up sufficiently to maintain them in position. Associated with the vertically reciprocating plate 3 are holding fingers which sustain the stack of papers as assembled. These fingers project inward from the post 4 and are movable outwardly to permit passage of the papers as they are added to the pile at the bottom, and are then quickly moved inward so as to put them underneath the stack of papers, thus retaining each paper in position as it is placed beneath the stack. To permit the holding or sustaining finger being in this inner position while the plate is dropping, the plate is provided with notches, as 38. in its edges, located to conform with the position of the paper holding fingers.

I have shown two types of paper holding fingers. One type consists of arms or bars 40, which are pivoted at their lower ends, as at etl, and have an off-set finger, as 412. at their upper ends. These fingers 421101 mally project inward beyond the inner faces of the retaining bars 4, enough to supply ample support for this edge of the stack of papers. The arms 4E0 are normally drawn inward by the action of the spring 42C. The lower surfaces of the supporting fingers 4 .2 are preferably on an incline, as is clearly shown in Figure 2, so that as the edge of the paper is being raised by the plate 3, engagement of thepaper therewith, will force the arm 40 outwarduntil the paper passes the point of thelterminal finger 4:2.

The other type of supporting fingers are shown at 4.3. These are mounted to reciprocate in suitable guides. Their reciprocation is secured by means of lever arms M, which are pivotally secured to a shaft 45, which shaft is oscillated in any suitable manner, as throughthe means of arms 4L6 secured thereto, moved through links or rods 47, whiclrare in turn reciprocated by a cam 48 carried by a shaft 49. This mechanism is so timed that the supporting fingers 43" are withdrawn just before the plate?) reaches their level and are returned to project under the paper before the plate starts to fall.

To prevent the papers,'as delivered from the accelerating belts to the plate 3, from rebounding, I provide stops, consisting of bars v5 mounted upon the arms 26, these being of an angular or L-shape and pivoted at 50 upon-the arms 26. This has an upwardly extending arm 51, which extends upward alongside of that edge of the stack of papers.

This arm has a. slot 52through which the shaft of the rollers 25, pass, thereby forming a stop to limit the downward drop of the part 5. The paper will pass easily under this but it will immediately drop down behind the paper, so as to prevent rebounding of the paper. v

1 In connection with the above paper stacking .mechanisms, ,1 have provided means whereby counting of the, papers is facilitated. uAs-a stop for the papers' when deliveredupon the table 3, Iprovide a plate 6, carried by an arm orarms pivoted to swing'towards, and from the paper receiving tables 3, as upon the pivot 61. Alongside .of

vthis is a toothed or ratchet wheel 63 having secured thereto a disk 64 which has a recess adapted toreceive a pin or roller 62 carried by the arm 60. The ratchet wheel 63 is intermittently turned through a pawl 65 carried by arm 66 which is "reciprocated through red 67, the latter being actuated in conformity with 'the addition'of the papers to the stack, through any suitable mechanism. IVhen the'disk 64: is in position to receive the roller 62, the plate 6 will be forced out- -ward from the table 3 beyond its normal posit on,'as is indicated in Figure 3, permit- "13111;? one paperto extend farther in this direction than the others. These projecting .papers will show in the stack and make counting out :of a definite number easy. A spring, as 68, acts to push arm 60 outward. To counteracttbe weight of the rcc1procating plate I show a spring 7 which acts,
